' y verve CONSTRUCTION.

To all whoml tmay concern 1 Be it known that we, EUGENE BUSH and .DOROTHY BUSH, citizens of the United States, residing at Washington, in the District of Columbia,have invented certain new and useful Improvements in Valve Constructions; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it apperv tains to .make and use the same.-

Our invention relates to valve construction and more articularly to float valves as commonl emp oyed upon flushing tanks of various "nds, and our prime object isto provide reliably etlicient means whereby the valve seat may be readily removed when worn and replaced without removing or disturbing the .other parts.

A further object, among others, is toprovide reliablyv ellicientmeans whereby the valve Seat -alone may bev quickly removed and regroundilif desired, or Areplaced with a dis. ischarge new seat wit out in the least de turbing the relationship of the pipe to the tank linin Other objects and advantages willbe hiere-k inafter made clearly apparent in the follow-A ing specification and by reference to the accompanying drawings, in which- Figure 1 shows our improved loat valve` com lete.

\ Fig. 2 shows aside view removed.

Fi 3 shows a top plan view seat illustrated in Fig. 2. i

Figs. 4' and 5 show another form of of our valve seat of the valve `mounting the valve seat.

In the construction of iloat Vvalves now in commonv use, the outlet tube 1s vrovided with an'upper flared end forming t e `valve seat and as said parts vare integrally formed'l Our purpose therefore is to provide a removable seat for theoutlet tube, which seat may be readily removed from its adjusted position for the purpose of being reground speeincauon of Letters Patent.

moval of the valve Seat proper is readily accomplished without the employment,v of a the incidental danger of movingthe outlet forA thatr purpose, thereby avoiding tube relative to the tank lining and contiguous parts. Furthermore, it will not be necessary to entirely empty the tank of water or cut off the water supply thereto in order to remove and replace our valve seat after 'it has become worn. In replacing the -valve of ordinary construction, it is notfonly necessary to turn oil' the water but to thoroughly Wipeout or dry'the linin of the tank prior to removing the outlet tu e. i

Referring in detail to the various parts of our -invention and coperatin accessories, numerals will be employed, the same numeral applying to a corresponding part in the several views.

Referrin in detail to the drawings, 1 indicates the ottom of a tank of the usual or any preferred construction, while' 2 designates the lining thereof and 3 the outlet tube of the valve havin the usual vent tube 4 extending upwardly in the tank above the normal water line. We prefer to form the integral extension 5 upon the outlet or dischargingtube 3 in which the ventrtube 4 may be seated `as by threading the Asame therein, it bein understood that the exten sion 5 is provi ed with a throat 6 to afford communication between the discharging als tube -3 and the vent tube 4, as is obviously necessary. n

The discharge tube 3 is rovided with the v enlarged'terminal or hea indicated-b the numeral 7, thereby aliording a shoul er 8' lmounted-in the bottom of the tank substantially in the usual manner as by the lock nut 11 coperating with the exterior threads 12 of said discharge tube, whereby the parts may be Securely locked together. We prefer also to interiorly thread the upper end of the head or extension 7, whereby the threaded body portion 13 of our valve Seat 1 0 may be received and forced in close contact with the sealing gasket 14 seated upon an annular shoulder within the head or extension 7, as will be desirable. The peculiar location thus provided for the sealing gasket 14 is of such character as to prevent the If desired, the threads ofthe bodyT portion 13 may be dispensed with and in lieu thereof two or more inclined ribs or mutilated threadsl ma be formed thereon, the in-A clined upper aces of `which are designed to pass under corresponding faces of the proJection of lips 16 carried by a` contiguous,

part of the interior wall ofthe head 7, it eing understood that thejinterior threads are also-omitted.I This constructionis illusi trated in detail in Figs, 4 and 5 asuwm`cbe observed. f

it wiiibeunderstopd that tw'o ffin if the coperating devices 15 and 16 niayjbe provided at equidistant oints andithat'- a the parts 15 and 16 have been brought .into

engagement with each other will therefore be all that is required to securelyv lock'the 'seat in an adjusted position or e'rmit'said lseat to be removed., We there ore reserve the right to employ either the threads re'- ferred to for seating our removable valve seat or the coperating members 15 and'16 as vwe may nd most satisfactory in practice, and we therefore do not wish to be confined to either method.

Ordinarily it will be found practical for the operator to quickly remove our im roved valve seat by grasping the same with the hand, but in the event of this operation being `diiiicult from any cause, the interiorly projecting lugs 17 are formed upon the valve seat to facilitate the removal thereof by a Spanner wrench or other suitable means.

We are aware that it is old to provide removable valve seats for various kinds of valves but we desire to call attention to the simplicity of construction which we have adapted in providin a removable seattfor a float valve,'inasmuc as the use of our improvedvalve renders it wholly unencessary to disturb the relationship of the discharge tube and the tank or rthe linin` thereof after the said discharge tubeA has been locked in place. ,In practice, it has been found, when the locking or follower nut 11 is released and the discharge tube removed for the pur' poseof replacing it with a new one, that the separation ofthe asket from the contiguous part of the tank inin will disclose such a corroded condition of t e lining as to render the entire tank of no further use until a new linin has been replaced therein, whereas if the ischarge tube had not been disturbed relative to the tank lining, the life and usefulness of the tank could have been preserved many years longer, especially since in removing the discharge tube 3, it is necessary to empty the tank of its contents and carefully wipe the lining thereof dry, which act of drying incidentally loosens the corroded spots in the lining and thereby causes general leakage thereof. I

It follows therefore that by providing a.

'valve seat which may be quickly removed' and replaced, it is rendered wholly unnecessary to disturb the relationship of the diseiinitely, thereby rendering vthe services of an expert plumber unnecessary, a most important desideratum. Moreover, attent' 'lev vcharge tube and the tank lining, thusmak-v l ing'it possible to continue the use of the tank- 1n 75 tionis called to the fact that in removing the entire discharge tube, its connection with the spud of the closet often entails a lar e tional work and expense.

Our improved valve is mounted in the y'meansof the follower nut 11 a er the gasket 9.v ,TheA float valve 18 is provide instances the action of the water upon the amount of damage and consequent ad I usual manner by locking the same in osition very limited rotation of t e valve seat after b with the usual controlling stem.` 19 cperatf in with the bracket or arm 20. uponthe tubuar vente. It is well known .thatin'some valve seal isso destructive that the eiliciency of the valve is destroyed in a few months,

whereby a continual leakage results.` In the old form of valve it is necessary to call 1n the services of an expert plumberto remedyA the defect, whereas by. `the use of'A our improved valve having an easily removable seat, the layman mayL quickly vremove the seat and have it reground or he can replace it with another seat urchasablein the open market as part of his supplies. We desire therefore to call particular attention to the importance of leavin the discharge tube and the lining of t e tank undisturbed,

whereby the usefulness of said partsis con- 4 tinued practically indefinitely, ourimproved valve seat rendering said disturbance wholly unnecessary and at the same time providing means for easily preventing all leakage of the valve, as above set forth.

While we have described the preferred l construction and combination of parte, we wish to comprehend in thisapplication all substantial equivalents and substitutes that may be considered as falling fairly within the scope of our invention, and we therefore do not wish to be confined strictly to the exact showing herein presented. Believing i that the advantages, construction and manner of using our invention have thus been made apparent, further description is deemed unnecessary.
